Access to services

Starting 1 January 2019 researchers can apply for (limited amounts of) computing time directly via SURFsara. This applies to cloud and cluster computing on HPC Cloud, Lisa, Cartesius Supercomputer and Grid. More information about how the national compute facilities can help with your research question? Contact us via the button 'Obtain Access'.

Obtain access 

Are you familiar with the capabilities of the national compute facilities? Download the Application Form Cartesius and Lisa, fill it out and send it to directly.

  • maximum of 100,000 core hours Cluster computing (on Lisa Compute Cluster including 200 GB directory storage, 4 hours support)
  • maximum of 500,000 core hours Cluster computing (on Cartesius Supercomputer including 200 GB directory storage, 4 hours support)

Or fill out the online Application Form HPC Cloud and Grid directly to apply computing time:

  • maximum of 50,000 core hours Cloud computing (on HPC Cloud, including 2 TB storage, 4 hours support)
  • maximum of 500,000 core hours Data Processing (on Grid, including 200 TB disk space, 300 TB tape storage, expertise needed to set up infrastructure)

NOTE: The total budget for computing time applications within the SURF Compute Call 2019 is limited. You can only apply within the described range per system, and only one time each year for a specific research project. Other options are:

Access to all other services for research

Do you need data services to store or share data during or after your research (i.e. Research Drive)? Please contact or the research support department of your faculty or institution.

Do you want to request access to other services, such as big data analytics, visualisation, connectivity, or consultancy? Go to the specific pages for those services (see overview).

Need compute power more often?

Some institutions have organised direct access to national compute facilities for their researchers. They provide access to SURF compute and data services via a RCCS-contract. This way you will be able to speed up your analyses 10, 100, 1000 times or include many more parameters than you normally could.

Researchers from these institutions already have direct and easy access to compute power and data services via their IT department or research support office:

Need larger amounts of computing time? Via NWO

Large scale research projects need to apply via NWO. Need more than 50,000 core hours on HPC Cloud; 100,000 core hours on Lisa Compute Cluster; 500,000 core hours on the supercomputer Cartesius or more than 500,000 core hours (and 200 TB disk space, 300 TB tape storage) on Grid? Apply for Computing Time on the NWO website.

SURFsara gladly supports you to the correct request route to national facilities. Please send your email to

Who can apply?

Access to national compute facilities can only be applied by researchers with a permanent contract or researchers with a temporary position at these research institutes (members of the SURF Cooperative: all universities, umc's, research institutes and hbo's/universities of applied science, except for mbo's). Note: applications from researchers with a temporary position may need a signature as guarantee from a supervising staff member with a permanent contract. By signing the application the supervising staff member declares that they are responsible for the awarded computing time after the expiration date of the project.

Technical support

Integrating the SURF service portfolio into your institution?

Would you like to integrate the range of services for researchers offered by SURF with the services offered by your institution? This will allow you to offer researchers at your institution 1 central research support desk for ICT services. Then please contact the Support4research team via

The most important goal of the Support4research project is to ensure that the support provided by SURF meets the needs of the research community at education and research institutions.

Direct and structural access via an RCCS contract

Research Capacity Computing Service (RCCS) is the SURF insourcing service unit that directly connects computing systems to the institutions connected to SURF. Via RCCS, institutions can offer their employees direct access to the computing systems and SURFsara expertise. In order to do this, institutions buy credits beforehand.
